.To all whom, it may concern.-

Be it known that I, FRIEDRIOH'WILHELM IDEN, poultry breeder, a subjectof the King of Prussia, Emperor of Germany, residing at Mariendorf, nearBerlin, in the Kingdom of Prussia and Empire of Germany, have inventedcertain new and useful Improvements in Incubators with Egg-TurningMechanisms, of which the following is a full, clear, and exactdescription.

The invention relates to improvements in incubators, of which thefollowing is a full and clear description, reference being had thereinto the accompanying drawings.

The principal condition of an effective incubator is a uniformdistribution of heat and moisture in the hatching-air in order to exposethe eggs on all sides to the same moisture and temperature. The deviceshitherto used are insufiicient for this purpose, and the presentinvention reaches this aim in another way by giving oif the necessarymoisture.

In the accompanying drawings, Figure 1 is a section through thehatching-room with the revoluble eg -boxes, in which the eggs are turnedby a device which is operated by hand; Fig. 2, a section on the lineA Aof Fig. 1.

1 is a casing in which a shaft 2 is revolubly journaled. Wheels 4 arekeyed to this shaft 2, to which motion is imparted by a rope or beltpassing over pulleys 26 27. Between the wheels 4 the egg-boxes 6 arejournaled. The egg-boxes 6 consist of frames, in which revoluble rollers7 are parallelly journaled in equal intervals, so as to form a grate orgraduated screen. The rollers 7 are provided at their ends with pinsturning in the frames. The rotation of the egg-boxes 6 may be effectedin some different way, and the egg-boxes may make at the same timerevolutions in several directions. In the modification shown by Figs. 1and 2 the egg-boxes 6 are suspended in the mode of a swing-boat betweenthe rims 4 and turn loosely around the shafts 11, so that these boxes 6in consequence of their own gravity are always directing downwardlytheir under surfaces when the shaft 2 is re- (No model.)

volved. In this manner the egg-boxes are continuously traveling throughthe whole hatching room. Besides their revolution around thehorizontally-journaled shaft 2 the egg-boxes 6 make a second revolutionaround the pins 12, by means of which the boxes6 are suspended on theshafts 11. The egg-boxes 6 are supported for this purpose by bails 13,on which the pins 12 are fastened. These pins 12 are formed in one piecewith sockets 14, by means of which the suspension to the shafts 11 iseflected. A bevel-wheel 15, keyed to the pin 12, meshes with the toothedwheels 16 on the shafts 11. If the shaft 2, with the wheels 4, carryingthe egg-boxes 6, is rotated, wheel is rolling on the other wheel 16,turning round itself with the wheel 4, and therefore motion is impartedto the boxes 6, so that these boxes are forced to pass through the Wholehatching-room around the shaft 2 and to rotate at the same time aroundthe axis of the suspending-pins 12.

For the purpose of enriching the air introduced into the hatching-roomwith a certain quantity of moisture a moistening device is arranged inthe hatching-room. This device consists of a trough 21, containing watertraversed by an endless ribbon 22. This ribbon is conducted over therollers 23, moved through the hatching-room by means of the roller 24,and pressed at the same time against the roller 24 by the roller 30,which is held downward by a spring. In this manner continuous movementis imparted to the ribbon 22 by the two rollers 24 30. A rope pulley 26is fastened to the shaft at the outside of the hatching-room, its motionbeing transmitted to another pulley 27 on the shaft 2 by means of a ropeor belt. If, therefore, the shaft 2 is revolved, the shaft 25 islikewise rotated, and simultaneously the moistening-ribbon 22 isadvanced through the hatchingroom, whereby sufficient moisture isevaporated and communicated to the heated air.

As soon as the chicks are hatched they may be removed to a brooding-roomespecially built for this purpose.
